Summary

The USS Charleston, an Independence-class littoral combat ship, conducted a transit near Sabina Shoal in the South China Sea on October 20. China's military claimed the vessel illegally intruded into waters adjacent to the disputed shoal and reported deploying naval forces to monitor the American warship. The US Navy stated the USS Charleston was conducting routine operations in international waters consistent with international law and rejected China's assertion that authorization was required for passage through the region. The incident occurred at Sabina Shoal, a location not held by China, and marks the first public acknowledgment by the People's Liberation Army Navy of following an American ship near a site outside Chinese control. The Philippines stated the American vessel did not violate Chinese territory. The incident was not confirmed by US Pacific Command.
